Hi,
No, it is not impacted. We have tested it manually and verified by code inspection. The vulnerability in the reference implementation is caused by using an unsigned int when indexing the input. The Mbed TLS implementation does not do that.

Is the SHA-3 impacted by the vulnerability reported in NIST vulnerability database (link below) ? https://nvd.nist.gov/vuln/detail/CVE-2022-37454
“Description The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface. “
